572 校准仪校准器

Enhancements to 5700A/5720A ac voltage output capability provided by the 572:

• 
  Frequency limits at higher voltage increase to 100 kHz at 750 V, 30 kHz at 1100 V
  


• 
  Load limits are to 70 mA for frequencies above 5 kHz, and to 50 mA for frequencies less than 5 kHz
  


• 
  Capacitive load limits are increased to 1000 pF
  

Voltage
output from the 572 is available at the 5700A Series Calibrators'
front or rear binding posts. This eliminates the need to move cables
during a procedure that requires amplified as well as standard
calibrator outputs.福禄克572 Amplifier

The
572 front or rear panel OUTPUT binding posts are only for current
output. Extended-range ac and dc current is supplied through them. Since
most meters with a high current range use a separate high current input
terminal, this configuration normally eliminates the need to move
cables during a procedure. If a single-point current output is needed,
the 5700A Series Calibrator can be configured to source all current
outputs through the 572 binding posts.福禄克572 Amplifier
